Switched-mode buffer power supply for built-in PSB 13.8V/3A PSB-12V3A

Reliable backup power supply for security and automation systems

The Pulsar PSB-12V3A buffer power supply is a solid solution designed to provide uninterrupted power to devices requiring a stable 12V DC voltage. The device is perfect for alarm systems, access control, CCTV monitoring and other applications where continuous power supply is crucial. The switch-mode design guarantees high efficiency and minimizes energy losses.

The PSB-12V3A power supply offers an output current of 3A and an additional current of 0.5A for battery charging, ensuring long-term operation even in the event of a mains power failure. Built-in protections protect both connected devices and the power supply itself against short circuits, overloads, overvoltages and excessive battery discharge. LED optical signaling informs about the presence of mains voltage and battery charging status.

Versatile application and easy installation

The power supply is enclosed in a durable housing, which increases its resistance to mechanical damage and facilitates mounting. Compact dimensions (110 x 78 x 36 mm) allow installation in limited space. The possibility of mounting on a DIN rail (using optional DIN1 or DIN2 brackets) further increases installation flexibility. The set includes battery cables with angled lugs, which simplifies connection to the battery.

• High efficiency: 87% efficiency translates to lower energy consumption and less heat loss.
• Comprehensive protection: Short-circuit protection (SCP), overload protection (OLP), overvoltage protection (OVP) and over-discharge protection (UVP) ensure safe system operation.
• Battery charging: A built-in charging circuit with a current of 0.5A takes care of the proper battery charge level.
• LED signaling: Intuitive optical signaling informs about the operating status of the power supply and battery charging.
• Universality: A wide range of AC input voltage (200-240V) allows operation in various network conditions.
• Ready for mounting: The set includes battery cables with angled lugs to facilitate connection.

The Pulsar PSB-12V3A buffer power supply is a reliable solution for professionals and users who value the stability and safety of their device power supply. Thanks to its high-quality workmanship and rich equipment, it is an ideal choice for a wide range of applications.
